Compared with other classic speech enhancement algorithm
buit-in pre-whitening subspacealgorithm has a good denoising effect
but in a low signal-to-noise ratio environment
there is still a large amount of residual noise. For this
the method that combining signal subspace optimization andwiener filtering is put forward to improve the speech quality. Simulation results show that underseveral common background noises with low signal-to-noise ratio
the performance of the proposedapproach ismore excellent
it can effectively restrain background noise and improve the speech quality
meanwhile
in some extent
guarantee the speech intelligibility
compared with the traditional spectral-subtraction
wiener filtering method
buit-in pre-whitening subspacealgorithm.
